The Luxpowertek 25.6V Li-7.5e 7.5kWh LV Lithium Battery 24V is a compact but high-capacity low-voltage storage solution designed for residential backup, off-grid systems, and smaller commercial energy applications that need dependable battery performance without moving into a larger 48V platform. Built with Lithium Iron Phosphate (LFP) cells, this battery offers strong safety, long cycle life, and stable daily performance for solar energy storage applications.
With a 7.5kWh rated energy capacity, 300Ah rated capacity, and 25.6V rated voltage, the Li-7.5e is well suited for buyers looking for a serious 24V lithium battery that can handle daily cycling and backup demands with confidence. It is a practical choice for homes, cabins, small businesses, and other power setups where consistent storage and efficient battery management matter.
The Li-7.5e is also designed with scalability in mind. It supports 140A charge current and 140A discharge current, communicates through CAN / RS485, and can be connected in parallel with up to 35 units. That gives installers more flexibility when designing larger battery banks or preparing a system for future expansion. This is especially important for customers who want to start with one battery and grow the system later as power needs increase.
From an installation perspective, the battery offers useful flexibility. It can be used in rack-mounted, wall-mounted, or floor-standing setups, making it easier to fit into different battery room layouts and equipment spaces. The battery measures 463 Ă— 452 Ă— 225 mm and has a weight of 53.5 kg, which is important for transport planning, mounting requirements, and overall installation design.
The battery is built for dependable indoor solar storage use, with an IP20 rating, operating temperature range of -20°C to +55°C, storage temperature range of -10°C to +35°C, and humidity tolerance of 5% to 85% RH, non-condensing. With its solid capacity, scalable design, modern communication options, and practical size, the Luxpowertek Li-7.5e is a strong choice for buyers searching for a reliable 24V 7.5kWh lithium battery for solar backup and off-grid energy storage.
